Some things to check:
1. confirm the extra memory is working by using xmdstub/xmd and
2. the kernel link script linux-2.4.x/arch/microblaze/mbvanilla.ld
describes the size of the OPB memory segment (but unlikely to be causing
your crash). If you change this, make sure you delete the file
linux-2.4.x/linux.ld before rebuilding the kernel.
3. The cacheable address range (in system.mhs) matches the 16Mb address
space - so you might want to boost that up as well. If you mess with
the actual cache size (tag bits etc) then you'll also need to modify
If I think of anything more I'll let you know.
